ANALYSIS OF THE PROCESS OF THERMOSTABILIZATION OF A HIGH-TEMPERATURE SURFACE WITH DISPERSED FLOW

Experiments have been performed to investigate the effi ciency of the process of thermostabilization of a hightemperature surface with dispersed fl ow of a heat transfer agent at a pressure of 0.2–0.6 MPa in it and at a mass rate of fl ow of heat transfer agent of (3.3–6.15)·10^–3 kg/s and a surface sprinkler density of 1.67^–3.11 kg/(m² ·s). Assessments have been made of the amount of heat transfer agent evaporating in all investigated heat transfer regimes. An equation describing various heat transfer regimes has been obtained for heat transfer from a hightemperature surface to a dispersed fl ow of a heat transfer agent in a criterial form. Criterial equations qualitatively describe experimental data within a small error, which indicates their satisfactory reproducibility in the said range of regime parameters of the process
